Baldwin Filters PA3778 Air Filter

This Baldwin Filters PA3778 is an automotive engine outer air filter with a round design. It measures 12-1/2 inches in height and 5-1/4 inches in outside diameter. The unit is supplied as a new replacement element for compatible engine air intake systems.

Suits engines needing this exact round outer filter

Buyers who need a panel-style filter or an inner safety element cannot use this part. Vehicles requiring different dimensions or a complete housing assembly should look at other configurations. The filter is restricted from sale in certain states, so local regulations must be checked first.

Round design with 12-1/2 inch height

The round profile and 12-1/2 inch height are the critical dimensions that determine fitment. Matching these specifications to the engine manufacturer's requirements confirms whether this is the correct part. Verification against the original equipment reference is essential before installation.

Questions about this item

How can I confirm the Baldwin Filters PA3778 air filter is installed and sealing correctly?

After installation, start the engine and check for any whistling or air-leak sounds around the housing; a smooth idle and normal boost pressure indicate the 12-1/2 in round element is seated and working as intended.

What comes with the PA3778 and what must I source separately?

The box contains the Baldwin Filters PA3778 round outer air filter element only; mounting hardware, housing clamps or any inner filter are not included and must be supplied from the existing assembly.

Which version of the PA3778 should I select for my application?

The PA3778 is offered in a single 5-1/4 x 12-1/2 in size; match these dimensions and the round outer-element design to your equipment specifications to ensure the correct fit.
